Hi Experts,
I want to convert a Visual Basic 2010. It is now targered for framework 3.5 and I want to use framework 4.0. Everything works fine except for the Crystal Reports modules. They are still dependent on v.2.0.50727. I have installed the newest version of Crystal Reports 2010 for Visual Studio (it's called Crystal Reports for Framework 4.0).
I know there is a workaround by adding some code to app.config to make the runtime work in a kind of legacy mode, but that is not what I want.
I thought it is possible to run Crystal Reports in a true framework 4 environment. What am i doing wrong?

Thanks for the reply.
As you probably noticed in the image I attached to my previous posting, I do use version 13.
Actually I build my reports in Crystal Reports 2008 (which is version 12) and I show them using the reportviewer of Crystal Reports for Visual Studio 2010 (= version 13).

to my config file does the trick. This solution is probably not that bad because .NET 4 is uses when possible and lower versions are only used when the higher version does not work.
So why bother? Well, I don't like the idea of using legacy modes, when there is no need to.
When the latest version of CR for VS is able to work in full .NET 4 mode, I would like to accomplish this, but I still don' know how.
Even when I start a new project and I only add the necessary code to show a basic report, I get the same error.
